Ok, here's my grain of sand. I don't know what geomajas is, so I don't
know how much Flex would impact on this.
I've been working with Flex from the past two years or so, now a days
a little less intensive, but still working. I've worked with two or
three map API's for Flex and I have to say that totally worth it.
About the speed, I haven't seen any benchmark bu ActionScript3 should
of data, wether you use raw XML or some other technology such as AMF*.
About the downside Pieter mention there, I think in these days, the
Flash plugin is something you should have on a browser, it is not a
strange requirement anymore. However, you shouldn't confuse Flash with
Flex, even when a Flex application is a Flash movie, their are used
for completly different things and can work togheter since you can,
from Flex, use resources from an swf made in Flash.
Anyway, my opinion is: "go for it if your UI is complex enough", Flex
allows you to build a really complex, advanced UI with advanced
widgets that looks, performs and behaves really good. Programming AS
not to mention modularization possibilites with Flex Modules and
Libraries also, you should reduce the browser compatibility issues in
a 95% at least.
Hope it helps.
